As we wrap up IBC 2026, we find ourselves looking back on more than just four days in Amsterdam. At our booth (5.B55), OvenMediaEngine brought together people from different corners of the industry, each with their own challenges, ideas, and visions for what live streaming could become.

AV1 delivers similar quality to H.264 at about half the bitrate. But if you serve only AV1, viewers whose devices cannot play it get no video at all. Support also varies by browser and by protocol (LL-HLS or WebRTC). This post shows how to solve this with a multi-codec setup: OvenMediaEngine produces both AV1 and H.264 from a single input (H.264 or AV1), and each client picks the codec it can play.

If you have AV1 output running from our previous post, What Are the Benefits of AV1?, and are preparing a commercial service for a wide range of devices, the sections below walk you through checking device support, a multi-codec configuration, client-side codec selection, and a phased rollout.

AV1 can deliver the same picture quality as H.264 at about half the bitrate. For a live service, where delivery traffic grows with every viewer, that is the most direct way to cut CDN costs. And you do not have to change how you broadcast: keep sending H.264 from OBS or your existing encoder, and let OvenMediaEngine convert it to AV1 for viewers.

If you are evaluating AV1 for a live service on OvenMediaEngine (OME), this post walks you through the numbers, the hardware you need, and a working configuration for LL-HLS and WebRTC.

What an operator wants to know at 3 a.m.

Many operators keep a player running and watch the broadcast to decide whether the service is healthy. That is necessary work, but a player shows only the one rendition currently selected out of the several quality levels generated for the same broadcast. All it tells you is that this one rendition looks fine over the network you happen to be using. It cannot tell you whether only the transcoding step that produces 360p on the server is falling behind, whether only viewers in another region are buffering, or whether a backlog inside the server is accumulating into seconds of latency for viewers. By the time something looks wrong in the player, viewer complaints have already come in.

While a broadcast is running, there are three things an operator actually wants to know.

1. Is the service healthy right now?
2. If it is not, what is wrong?
3. Is it an ingest problem (the direction from the encoder into the server), a server problem, or a problem for only some viewers?

Answering all three means seeing, in one place, the state of the input streams, the server's internal processing, and the traffic going out to viewers.

Making a live channel redundant comes down to one thing: keeping the output of the two Origins behind your CDN, Primary and Backup, synchronized so that the player can switch between them at any time and keep playing without interruption.

With VOD this is easy. The files are pre-rendered and static, so any Origin serves the exact same bytes, and putting Primary/Backup behind a CDN is all it takes. Live is different. Each Origin cuts the stream into segments in real time, so even when both receive the same broadcast, their output does not line up on its own.

This post covers what has to line up to make a live channel truly redundant, and in particular how to synchronize the encoder-origin path.

Starting with the next release, the open-source edition of OvenMediaEngine will no longer provide hardware-accelerated features, including hardware encoder integrations such as NVIDIA. This was a difficult decision, and we want to begin by thanking everyone who has relied on these features over the years and asking for your understanding. Software-based features, including software encoding, remain fully supported, and no other features are affected.

RTSP has been the de facto protocol for IP cameras for over two decades. Almost every CCTV, IP camera, and network video device on the market speaks RTSP natively. It works well on dedicated NVR appliances and desktop clients. But the moment you try to bring those streams into a modern web or mobile dashboard, the cracks start to show.

The OvenMedia Labs blog is now hosted directly on our own domain. Going forward, deep dives into sub-second latency live streaming, OvenMediaEngine release notes, and field-tested guidance will all land here first.

OvenMediaEngine is an open-source and sub-second latency streaming server capable of handling large-scale and high-definition streams. It can be installed and used in various environments, such as servers, CDNs, and Clouds. Today, we will show you how to easily use OvenMediaEngine by installing Docker on an AWS EC2 instance.

Live streaming has grown rapidly to the point where it has become a part of many people’s daily lives. This growth is further accelerated due to the increasing demand for online media consumption by users.
